Abstract
The present invention is directed to a method for cloning and producing the XmaI restriction endonuclease by (1) introducing the restriction endonuclease gene from X. malvacaerum into a host whereby the restriction gene is expressed; (2) fermenting the host which contains the plasmid encoding and expressing the XmaI restriction endonuclease activity, and (3) purifying the XmaI restriction endonuclease from the fermented host which contains the plasmid encoding and expressing the XmaI restriction endonuclease activity.
